Relativity of simultaneity in secondary school: an analysis based on the theory of the conceptual fields
(Universidad de Patras, 2018-07)
In this paper, we present results about the conceptualization of the relativity of simultaneity and the operational invariants used by high school students. The Theory of Conceptual Fields is adopted to design, analyse and ...
Best simultaneous L p-approximation on small regions
(Taylor, 2015-01)
In this article, we study the behavior of best simultaneous L p-approximation by algebraic polynomials on a union of intervals when the measure of them tend to zero. We also get an interpolation result.
Simultaneous unitary neuronal activity in both superior colliculi and its relation to eye movements in the cat
(1986)
The analysis of simultaneous unitary neuronal activity related to eye movement and recorded in both superior colliculi has shown a mirror-functioning image. Increase of the frequency discharge in a collicular unit, was ...
Simultaneous optimization by neuro-genetic approach for analysis of plant materials by laser induced breakdown spectroscopy
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
A simultaneous optimization strategy based on a neuro-genetic approach is proposed for selection of laser induced breakdown spectroscopy operational conditions for the simultaneous determination of macronutrients (Ca, Mg ...
Statistical design-principal component analysis optimization of a multiple response procedure using cloud point extraction and simultaneous determination of metals by ICP OES
(Analytica Chimica Acta, 2006)
A procedure has been developed for the simultaneous determination of traces amounts of Cd, Cr, Cu, Mn, Ni and Pb from saline oil-refinery effluents and digested vegetable samples using inductively coupled plasma optical ...
Determination of Cr, Fe, Co, Ni, Cu, Zn, As and Pb in liquid chemical waste by energy dispersive X-ray fluorescence
(SPRINGER, 2011)
A method for simultaneous determination of Cr, Fe, Co, Ni, Cu, Zn, As e Pb in liquid chemical waste using Energy Dispersive X-Ray Fluorescence (EDXRF) technique was evaluated. A small sample amount (200 mu L) was dried on ...
Best Simultaneous Monotone Approximants in Orlicz Spaces
(Taylor & Francis, 2013-01)
Let f = (f1, , fm ), where fj belongs to the Orlicz space [0, 1], and let w = (w1, , wm ) be an m-tuple of m positive weights. If ⊂ [0, 1] is the class of nondecreasing functions, we denote by ,w(f, ) the set of best ...
